In short
Benzyl cinnamate is an ester found in Peru and tolu balsams. It has a faint, sweet balsamic odour and is used as a fixative.
What Benzyl Cinnamate smells like
Benzyl cinnamate has a sweet, balsamic odour and a honey-like taste, in chemical references. Fragrance suppliers add floral and spicy facets — sweet, spicy and floral with a powdery balsamic nuance, or creamy and slightly floral with a hint of spice — and one lists its odour as sweet, balsamic and very weak. It is a quiet base note and a mild fixative, used in heavy, oriental perfumes and floral-amber bases. It occurs in Peru and tolu balsams.

What makes Benzyl Cinnamate distinctive
Balsam with almost no voice: a faint, creamy sweetness that holds other notes rather than being smelled itself.
How Benzyl Cinnamate is used
Used as a mild fixative in oriental, amber and floral-amber bases, and in balsam reconstructions.
Typical role: fixative (slow to evaporate; helps a blend last and holds lighter notes).
How Benzyl Cinnamate differs from similar materials
- Cinnamyl Cinnamate
- Cinnamyl cinnamate is even fainter and more resinous, with jasmine and rose; benzyl cinnamate is a creamy, slightly spicy balsam.
- Peru Balsam Oil
- Peru balsam contains benzyl cinnamate and benzyl benzoate, and adds vanilla, cinnamon and amber; benzyl cinnamate alone is a faint, creamy balsam. (compared directly by a cited source)
- Cinnamyl Acetate
- Cinnamyl acetate is a clearly perceptible warm, sweet floral; benzyl cinnamate is a faint, creamy fixative.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.

Safety and compliance
The IFRA Standards Library lists a Standard covering Benzyl Cinnamate:
- "Benzyl cinnamate" — Restriction, 49th Amendment, published 2020-01
Limits differ by product category and are set out in the Standard itself; this page does not reproduce them. The list above reflects the library as read on 19 October 2026.
Benzyl Cinnamate is one of the 26 fragrance allergens listed individually in Annex III of the EU Cosmetics Regulation (label name: Benzyl cinnamate), which must be named on cosmetic labels above 0.001% in leave-on and 0.01% in rinse-off products. Regulation (EU) 2023/1545 extended the list; see the fragrance allergens list.
Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (1,794 reports): H317 may cause an allergic skin reaction (99.8% of reports); H411 toxic to aquatic life with long lasting effects (99.5% of reports). A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
This page is general information, not a safety assessment or a specification. Confirm identity, composition, IFRA status and allergen content from your supplier's documents for the lot you hold.
